The internal arrangements of the pyramid are of the simplest character; they consist of a granite-built passage carefully concealed in the north face, running at first at an angle of 25°, and then horizontally, until stopped by a granite barrier at a point which indicates a change of direction; a second passage, which begins on the outside, at a distance of some yards in advance of the base of the pyramid, and proceeds, after passing through an unfinished chamber, to rejoin the first; finally, a chamber hollowed in the rock, but surmounted by a pointed roof of fine limestone slabs. The sarcophagus was of granite, and, like that of Khufu, bore neither the name of a king nor the representation of a god. Of Khaf-Ra’s sons, Men-kau-Ra (the Mycerinus of the Greeks), who was his successor, could scarcely dream of excelling his father and grandfather; his pyramid, “the Supreme” (Her), barely attained an elevation of 216 feet, and was exceeded in height by those which were built at a later date. Up to one-fourth of its height it was faced with syenite, and the remainder, up to the summit, with limestone. For lack of time, doubtless, the dressing of the granite was not completed, but the limestone received all the polish it was capable of taking. The enclosing wall was extended to the north so as to meet, and be of one width with, that of the Second Pyramid. The temple was connected with the plain by a long and almost straight causeway, which ran for the greater part of its course upon an embankment raised above the neighbouring ground. The arrangement of the interior of the pyramid is somewhat complicated, and bears witness to changes brought about unexpectedly in the course of construction. The original central mass probably did not exceed 180 feet in breadth at the base, with a vertical height of 154 feet. It contained a sloping passage cut into the hill itself, and an oblong low-roofed cell devoid of ornament. The main bulk of the work had been already completed, and the casing not yet begun, when it was decided to modify the proportions of the whole. Men-kau-Ra was not, it appears, the eldest son and appointed heir of Khaf-Ra; while still a mere prince he was preparing for himself a pyramid similar to those which lie near “the Horizon,” when the deaths of his father and brother called him to the throne. What was sufficient for him as a child, was no longer suitable for him as a Pharaoh; the mass of the structure was increased to its present dimensions, and a new inclined passage was effected in it, at the end of which a hall panelled with granite gave access to a kind of antechamber. The latter communicated by a horizontal corridor with the first vault, which was deepened for the occasion; the old entrance, now no longer of use, was roughly filled up.
